  • Testing on blackberry device - adding and removing app multiple times

    - by Kai
    It would be useful for many people to know how to completely remove an application from your device when testing. I have downloaded my app many times now, and likewise have deleted it many times. The problem is when deleting the app, it does not remove things like the persistent object related to my app, or the images downloaded through the app. So, when I download the next build, I have no idea if something broke that is related to building the persistent object or fetching the images since those elements already exist from the last build. I don't know if this is a cache thing. I don't know if this is expected and I have to use some utility to wipe this data after deleting the app. I can't really find much info through basic web searches. Any information would be appreciated. Blackberry Bold 9000. 4.6 OS. tested with both SD card and no SD card.

  • How to batch retrieve documents with mongoDB?

    - by edude05
    Hello everyone, I have an application that queries data from a mongoDB using the mongoDB C# driver something like this: public void main() { foreach (int i in listOfKey) { list.add(getObjectfromDB(i); } } public myObject getObjFromDb(int primaryKey) { document query = new document(); query["primKey"] = primaryKey; document result= mongo["myDatabase"]["myCollection"].findOne(query); return parseObject(result); } On my local (development) machine to get 100 object this way takes less than a second. However, I recently moved the database to a server on the internet, and this query takes about 30 seconds to execute for the same number of object. Furthermore, looking at the mongoDB log, it seems to open about 8-10 connections to the DB to perform this query. So what I'd like to do is have the query the database for an array of primaryKeys and get them all back at once, then do the parsing in a loop afterwards, using one connection if possible. How could I optimize my query to do so? Thanks, --Michael

  • IOC Container that can target .NET Framework Client Profile?

    - by Rox Wen
    On our current WPF project, we've been performing dependency injection using the Ninject IOC tool. We want to target the .NET Framework Client Profile for a better download/install experience. The problem is that Ninject seems to reference libararies such as System.Web which are NOT in the Client Profile. Can anyone recommend an IOC container that can target the .NET Framework Client Profile (3.5 or 4) ?

  • Multithreading with STL container

    - by Steven
    I have an unordered map which stores a pointer of objects. I am not sure whether I am doing the correct thing to maintain the thread safety. typedef std::unordered_map<string, classA*>MAP1; MAP1 map1; pthread_mutex_lock(&mutexA) if(map1.find(id) != map1.end()) { pthread_mutex_unlock(&mutexA); //already exist, not adding items } else { classA* obj1 = new classA; map1[id] = obj1; obj1->obtainMutex(); //Should I create a mutex for each object so that I could obtain mutex when I am going to update fields for obj1? pthread_mutex_unlock(&mutexA); //release mutex for unordered_map so that other threads could access other object obj1->field1 = 1; performOperation(obj1); //takes some time obj1->releaseMutex(); //release mutex after updating obj1 }

  • Programmatically triggering events in Javascript for IE using jQuery

    - by Dan Herbert
    When an Event is triggered by a user in IE, it is set to the window.event object. The only way to see what triggered the event is by accessing the window.event object (as far as I know) This causes a problem in ASP.NET validators if an event is triggered programmatically, like when triggering an event through jQuery. In this case, the window.event object stores the last user-triggered event. When the onchange event is fired programmatically for a text box that has an ASP.NET validator attached to it, the validation breaks because it is looking at the element that fired last event, which is not the element the validator is for. Does anyone know a way around this? It seems like a problem that is solvable, but from looking online, most people just find ways to ignore the problem instead of solving it. To explain what I'm doing specifically: I'm using a jQuery time picker plugin on a text box that also has 2 ASP.NET validators associated with it. When the time is changed, I'm using an update panel to post back to the server to do some things dynamically, so I need the onchange event to fire in order to trigger the postback for that text box. The jQuery time picker operates by creating a hidden unordered list that is made visible when the text box is clicked. When one of the list items is clicked, the "change" event is fired programmatically for the text box through jQuery's change() method. Because the trigger for the event was a list item, IE sees the list item as the source of the event, not the text box, like it should. I'm not too concerned with this ASP.NET validator working as soon as the text box is changed, I just need the "change" event to be processed so my postback event is called for the text box. The problem is that the validator throws an exception in IE which stops any event from being triggered. Firefox (and I assume other browsers) don't have this issue. Only IE due to the different event model. Has anyone encountered this and seen how to fix it? I've found this problem reported several other places, but they offer no solutions: jQuery's forum, with the jQuery UI Datepicker and an ASP.NET Validator ASP.NET forums, bug with ValidatorOnChange() function

  • Why does my ASP.NET user control's field value reset to 0?

    - by Innogetics
    In the code below, why does the groupId value reset to 0 during Page_Load event? Maybe perhaps the AccountGrid created with groupId 1 is not the one that is loaded to the page? public partial class AccountGrid : System.Web.UI.UserControl { int groupId = 0; public AccountGrid() { } // an aspx page creates AccountGrid with "new AccountGrid(1)" public AccountGrid(int groupId) { this.groupId = groupId; } protected void Page_Load(object sender, EventArgs e) { DataAccessFacade facade = new DataAccessFacade(); // groupId resets to 0 here... grdAccount.DataSource = facade.GetAccountsByAccountGroupId(this.groupId); grdAccount.DataBind(); } } In my page, I have public partial class Default : System.Web.UI.Page { public Default() { } public void Page_Load(object sender, EventArgs e) { ctlAccountGrid = new Views.Controls.Account.AccountGrid(1); // should I do databind? ctlAccountGrid.DataBind(); } }

  • Using UNC path as paths location in Mecurial IIS6 Server2003

    - by Chris M
    I'm running the latest Mercurial and Python 2.6; IIS6 is using the wildcard ISAPI method to attach the site to the Mecurial hgwebdir_wsgi [paths] \ = \\COMP3254\TestRepo\* [web] baseurl = / allow_push = * push_ssl = false style = monoblue The setup works perfectly if I reference the local drive E:\repo* but doesnt work if I specify the network as above; I've given the server (MERCDEV01$) full permissions on the shared folder on COMP3254, I can't think of any other reason it wouldn't work. Any ideas?

  • Why is dereferencing a pointer called dereferencing?

    - by optician
    Why is dereferencing called dereferencing? I'm just learning pointers properly, and I'd like to know why dereferencing is called that. It confused me as it sounds like you are removing a reference, rather than going via the pointer to the destination. Can anyone explain why it is called this? To me something like destination or pointed_to_value would make more sense.

  • ASP ListView: How do I access the data that is databound to the rows?

    - by Robert
    I want to access the data that was databound to my list view when handling list view events such as: protected void List_ItemDataBound(object sender, ListViewItemEventArgs e) or protected void List_ItemCommand(object sender, ListViewCommandEventArgs e) Inside the events, I can not access the data via somthing like Eval("ID") Currently we are using a very hacky solution: string id = e.Item.FindControl("lblID").Text; Where lblID is a hidden control that is populated with data in the aspx file using: <asp:Label ID="lblID" runat="server" Text='<%# Eval("ID") %>' /> My eyes bleed when I look at this, Is there a better way?

  • How to make pytest display a custom string representation for fixture parameters?

    - by Björn Pollex
    When using builtin types as fixture parameters, pytest prints out the value of the parameters in the test report. For example: @fixture(params=['hello', 'world'] def data(request): return request.param def test_something(data): pass Running this with py.test --verbose will print something like: test_example.py:7: test_something[hello] PASSED test_example.py:7: test_something[world] PASSED Note that the value of the parameter is printed in square brackets after the test name. Now, when using an object of a user-defined class as parameter, like so: class Param(object): def __init__(self, text): self.text = text @fixture(params=[Param('hello'), Param('world')] def data(request): return request.param def test_something(data): pass pytest will simply enumerate the number of values (p0, p1, etc.): test_example.py:7: test_something[p0] PASSED test_example.py:7: test_something[p1] PASSED This behavior does not change even when the user-defined class provides custom __str__ and __repr__ implementations. Is there any way to make pytest display something more useful than just p0 here? I am using pytest 2.5.2 on Python 2.7.6 on Windows 7.

  • Finding the attributes on the properties of an instance of a class

    - by Dan
    Given an instance of a class I want to set properties on attributes at runtime. So I tried this, but as far as I can tell this finds the attributes on the class not the instance, so any changes I make to the attribute properties have no effect. var properties = myObject.GetType().GetProperties(); foreach (object prop in properties) { var attribute =prop.GetCustomAttributes(typeof(MyAttribute), true)[0]; //attribute.MyProp do some stuff } If I try using type descriptor like below, there is no way of getting to the attributes on the properties. var myObject= (MyClass) object; PropertyDescriptorCollection props = TypeDescriptor.GetProperties(myObject); //There is no props[0].GetCustomAttributes(

    I want to pass a function that takes a parameter to the ThreadStart Constructor in C#. But, it seems that this is not possible, as I get a syntax error it I try to do something like this Thread t1 = new Thread(new Thread Start(func1(obj1)); where obj1 is an object of type List<string> (say). If I want a thread to execute this function that takes in an object as a parameter, and I plan to create 2 such threads simultaneously with different parameter values what is the best method to achieve this?

  • get all widgets inside an element

    - by peirix
    From the dojo documents on dijit.registry, I see the forEach method accepts a last parameter thisObject. But it doesn't way what that object is. Is it a dijit widget or a dojo object? I want to destroy all widgets inside an element (that will be replaced by AJAX) so they can be parsed again without conflicting id's. dijit.registry.forEach(function(w) { w.destroyRecursive(); }, dojo.byId("ajaxElement")); But this destroys ALL widgets on the page...

  • [bash] files indexed by production date

    - by caas
    Each day an application creates a file called file_YYYYMMDD.csv where YYYYMMDD is the production date. But sometimes the generation fails and no files are generated for a couple of days. I'd like an easy way in a bash or sh script to find the filename of the most recent file, which has been produced before a given reference date. Typical usage: find the last generated file, disregarding those produced after the May 1st. Thanks for your help

  • Are there any Objective-C / Cocoa naming conventions for properties that are acronyms?

    - by t6d
    I have an object that models an online resource. Therefore, my object has to store the URL of the resource it belongs to. How would I name the getter and setter? MyObject *myObject = [[MyObject alloc] init]; // Set values [myObject setURL:url]; myObject.URL = url; // Get values [myObject URL]; myObject.URL; or would the following be better: MyObject *myObject = [[MyObject alloc] init]; // Set values [myObject setUrl:url]; myObject.url = url; // Get values [myObject url]; myObject.url; The former example would of course require to define the property in the following way: @property (retain, getter = URL, setter = setURL:) NSURL *url;

  • How do you programmatically move the caret of a Flex TextArea to the end?

    - by Akinwale
    I'm trying to move the caret in a Flex TextArea to the end after appending some text from my code. I've looked through the reference documentation for TextArea and its underlying TextField but it appears there is no method provided to handle this. One approach I've tried is to set focus to the text area and dispatch a KeyUp KeyboardEvent with the event's key code set to the "End" key, but this doesn't work. Any ideas on how to do this? Thanks.

  • How do you override operator == when using interfaces instead of actual types?

    I have some code like this: How should I implement the operator == so that it will be called when the variables are of interface IMyClass? public class MyClass : IMyClass { public static bool operator ==(MyClass a, MyClass b) { if (ReferenceEquals(a, b)) return true; if ((Object)a == null || (Object)b == null) return false; return false; } public static bool operator !=(MyClass a, MyClass b) { return !(a == b); } } class Program { static void Main(string[] args) { IMyClass m1 = new MyClass(); IMyClass m2 = new MyClass(); MyClass m3 = new MyClass(); MyClass m4 = new MyClass(); Console.WriteLine(m1 == m2); // does not go into custom == function. why not? Console.WriteLine(m3 == m4); // DOES go into custom == function } }
